IMPROVED FUSE-HOOD FOR'SHELLS.

Specification forming part of Letters Patent No. 34,0d0, dated December 24, 1861.

.To all whom, t may concern:

Be it known that I, SYLvANUs Snwvnn, of Fitchburg, in the county of Vorcester and State of Massachusetts, have invented a new and useful device to be applied to the fuses for igniting shells, which I denominate a Fuse-Hood,7 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, taken in connection with the accompanying drawings, making part of this specification, in which* l Figure 1 is an elevation, and Fig. 2 a section, of the same, showing its application to the projectile patented by me November 13, 1855, tted with the combination fuse,? so called. Fig. 3 represents the application of the hood7 to the common metallic fuse-stock of aspherical shell. Fig. 4 represents the application of the hood to the common wooden fusestook in a spherical shell; and Figs. 5, 6, and 7, plans of the inside of the hood, showing the different forms of attachment to the different fuse-stocks before referred to.

The subject-matter of my invention consists of a new device which is designed to be applied to the fuses of shells where the fuse is ignited by the fire ofthe charge of the gun, and more particularly to shells for rifled cannon, where there is but little or no windage allowed to the projectile, in which case the fuse must be ignited by the flame after it leaves the muzzle ofthe gun. The device consists of a thin circular concave plate or disk placed concentric with and at a little distance from the outer extremity of the fuse, as is shown in the drawings, and is supported in that position byany convenient attachment to the fuse-stock. Its purpose is to deilcct or conduct a part of the fia-me in which theprojectile is enveloped after it leaves the muzzle ofthe gun, directly upon the fuse to insure its ignition. It has been found by experience that where there is no windage to the projectile the ignition of the fuse will rarely take place unless some dlevice of the nature of the hood is employed.

In the drawings, A represents the hood, made of thin brass or other metal of the form shown, and is placed over the fuse and is held in that position by any convenient arrange ment that will leave a free space between it and the fuse.

B is the fuse-stock.

C is the fuse-case,whicli contains the fusepowder D.

E, Fig. 5, represents three clasps, of thin plate metal, attached to the hood, by which it is fixed to the fuse-stock of the combination` fuse, as in Fig. 2.

F, Fig. 6, represents two short triangular studs attached to the hood, designed to be driven into the wrench-holes in the common metallic fuse-stocl, as in Fig. 3.

G, Fig. 7, represents three nails or pointsV attached to the hood, designed to be driven into the common wooden fuse-stock, as shown in Fig. 4.

These several forms of applying the hood to fuses of different kinds will sufficiently explain its use without further description.

WhatI claim as my invention, and desire to secure by Letters Patent, is-

The employment of ahood or other equivalent device, in combination with a fuse, substantially in the manner and for the purpose described. i
